Alpine Swiper

A seamless integration of Swiper with Alpine.js, providing reactive slider functionality through Alpine's directive and magic property system.

Inspired by Alpine Splide - a similar integration for the Splide slider.

Features

• x-swiper directive: Initialize and configure Swiper instances with Alpine.js reactivity
• x-swiper-event directive: Bind Swiper events directly to Alpine methods
• $swiper magic property: Access Swiper instance methods and state from anywhere in your Alpine components
• Alpine store: Track and manage all Swiper instances with reactive state updates
• Full Swiper support: Includes all Swiper modules and features out of the box

Installation

Method 1: NPM

# Make sure you have Alpine.js installed first
npm install alpine-js-swiper

Then import and register the plugin in your JavaScript:

import Alpine from 'alpinejs';
import AlpineSwiper from 'alpine-js-swiper';

// Register the plugin
Alpine.plugin(AlpineSwiper);
Alpine.start();

Method 2: CDN

Include the following script tags in your HTML file (order is important):

<!-- Alpine Swiper (includes Swiper bundle) -->
<script defer src="https://unpkg.com/alpine-js-swiper@1.x.x/dist/alpine-js-swiper.min.js"></script>

<div x-data="{ options: { 
  loop: true, 
  autoplay: { delay: 3000 }, 
  pagination: { clickable: true },
  effect: 'fade'
}}">
  <div x-swiper="options" class="swiper">
    <div class="swiper-wrapper">
      <div class="swiper-slide">Slide 1</div>
      <div class="swiper-slide">Slide 2</div>
      <div class="swiper-slide">Slide 3</div>
    </div>
    
    <div class="swiper-pagination"></div>
  </div>
</div>

Using Swiper Methods and Properties

<div x-data>
  <div x-swiper class="swiper">
    <div class="swiper-wrapper">
      <div class="swiper-slide">Slide 1</div>
      <div class="swiper-slide">Slide 2</div>
      <div class="swiper-slide">Slide 3</div>
    </div>

    <!-- Control buttons using $swiper magic -->
    <div class="controls">
      <button @click="$swiper.slidePrev()">Previous</button>
      <button @click="$swiper.slideNext()">Next</button>
      <button @click="$swiper.slideTo(0)">First Slide</button>
      
      <!-- Accessing reactive state -->
      <p>Current slide: <span x-text="$swiper.activeIndex + 1"></span> / <span x-text="$swiper.slides"></span></p>
      <p x-show="$swiper.isBeginning">You're at the beginning!</p>
      <p x-show="$swiper.isEnd">You've reached the end!</p>
    </div>
  </div>
</div>

Working with Events

<div x-data="{ message: '' }">
  <div 
    x-swiper 
    x-swiper-event:slide-change="message = 'Slide changed to ' + ($swiper.activeIndex + 1)"
    x-swiper-event:reach-end="message = 'Reached the end!'"
    class="swiper"
  >
    <div class="swiper-wrapper">
      <div class="swiper-slide">Slide 1</div>
      <div class="swiper-slide">Slide 2</div>
      <div class="swiper-slide">Slide 3</div>
    </div>
  </div>
  
  <p x-text="message"></p>
</div>

API Reference

x-swiper Directive

Initializes a new Swiper instance on the element. Accepts all Swiper parameters.

<div x-swiper="options"></div>

x-swiper-event Directive

Binds Swiper events to Alpine expressions. Event names should be in kebab-case (e.g., slide-change instead of slideChange).

<div x-swiper-event:event-name="expression"></div>

Common events:

• slide-change
• reach-beginning
• reach-end
• progress
• resize
• init

$swiper Magic Property

Provides access to the Swiper instance methods and reactive state.

Available reactive properties:

• activeIndex: Current active slide index
• isBeginning: Whether the slider is at the beginning
• isEnd: Whether the slider is at the end
• slides: Total number of slides
• progress: Current progress value (0-1)

You can also access any Swiper methods and properties through the $swiper magic.

Alpine Store: $store.swipers

The plugin creates an Alpine store to track all Swiper instances:

<div x-data>
  <!-- Access a specific swiper by ID -->
  <button @click="$store.swipers.getSwiper('my-swiper-id')?.slideTo(0)">
    Reset all sliders
  </button>
</div>

Browser Support

Alpine Swiper supports all browsers that are compatible with Alpine.js and Swiper.
